Poor Service and no Cost saving as advertised

I have had my Solar system in with Stage Zero for just over a week and I can not say I am happy with the service. It has taken them since it has been installed to get my system online, my batteries dont charge and have been on the same % since the day it went online. I bought the system on the promise of saving money but since day 1 i have only ever used Eskom power and perhaps the batteries for an hour as they never charge. So how do I save money if that's the case? The backup service when i log a ticket takes forever and never properly gets resolved as I have 3 tickets still open. I am not happy so far. This cost saving exercise is going to end up costing me R2k more pm.
